PERCENT_THREAD | Ratio describing the actual engagement of fastener threads. |
PIPE_OD | Outside diameter of a pipe of the same nominal size. |
PITCH_DIAM_END | Bottom of a cylinder along the threading whose diameter is half the distance between the crest and the root of the threading. |
PITCH_DIAM_START | Top of a cylinder along the threading whose diameter is half the distance between the crest and the root of the threading. |
STRAIGHT_DEC | Diameter of straight drill. |
STRAIGHT_DEPTH | Depth of straight drill. Available for tapered holes with blind depth option of straight drill. |
